Hello all.

>From the group's many discussions regarding LCD displays, several of you
recommended Hantronix LCDs.  Well, I went out and purchased the 16x2
HDM16216h5 display.  I downloaded most Hantronix's literature for their
character displays, but they are not quite clear, and there are some
contradictions.  For example, to initialize the LCD, the application note
goes through 3 function sets (with varying delays between commands), while
their Character Module Initialization sheet goes through 4 function sets,
while the Samsung data sheet (Hantronix provided the data sheet for Samsung
controllers, stating they are used in all of their character displays)
indicated only 1 function set.

As this if my first attempt to interface with an LCD, I tried each of the
suggestions, along with the other commands such as Display on/off, display
clear, and entry mode set, and many other variations.  I checked and
checked the hardware, and all seems well.  I have VL connected to a 10k
pot, and R/W is tied directly to ground (I ran out of I/O pins and
initially, I just want to write to the display).  I am using the PIC16C84.

Any tips/advice/suggestions?

Thanks to all in advance.
